Developing and maintaining bach is a lot of work. We have decided to keep bach free and embrace a business model based on Patreon: how much do you consider bach is valuable for you? If the answer is 0$, or if you cannot afford to pay any price, that's totally fine - we completely understand. But if you can afford to pay us as little as a cup of coffee per month, that would really help. In addition to keeping bach accessible for everybody, you'll also have exclusive access to prereleases, video tutorials, and more.
